During their two-month contribution to the coolstation/coolstation repository, Awfulworldkid developed and integrated two new combat mechanics using DM, focusing on enhancing gameplay realism and player decision-making. They engineered a head injury system that applies brain damage based on the severity of blunt melee attacks, directly tying combat outcomes to player actions. In a subsequent update, they introduced a leg blunt-hit mechanic that temporarily reduces mobility, carefully preserving existing head injury logic to avoid regressions. Their work demonstrated a strong grasp of combat mechanics and game development, with clear commit traceability and maintainable code that supports ongoing balance and feature expansion.
